CHARCOAL RETORTS & KILNS

Four Seasons Fuel manufacture Charcoal Retorts and Kilns to produce coal and charcoal.

Charcoal Retorts - Of any size to fit your budget. The retort systems offer a higher productivity and more efficient way of scaling up production than operating a larger number of small round kilns.

The total output of these retorts is around 350 - 400 kg per burn depending on the kind of wood species that are put to use. The burn time is 8 to 10 hours. This is a lot less than with round kilns.

Our Charcoal Retorts

We have our own charcoal retorts to keep charcoal production on site. We use the wood’s natural gases to reheat the retorts. By using the wood's natural gases to reheat the retorts the retorts offer significant advantages. The retorts systems offer a higher productivity and more efficient way of scaling up production than operating a larger number of small round kilns. Our retorts offer possibilities of more efficient use of raw materials. (i.e. 4 x1 ratio) is a normal for these retorts, (compared with the normal steel round kilns at 7 x 1 ratio)

The Retorts

The retorts are 6 ft depth x 11 ft wide x 7.5 ft high. There are 2 charge cylinders, each are 6ft long by 3ft 4 inches and together will give you roughly 250kg of charcoal per burn (depending on what wood you use).

The doors are made with 500mm of ceramic blanket sandwich in two plates of 4mm steel which help heat retention.

The gases exhaust on the doors. When the gases are exposed and rise they pass throough the vent in the door travel down in the fire box exhaust system this is made out from 8m s/steel tube with 4 exhaust ports which are pass though the fire bricks into the fire box then the gases reunite and rise up through the spaced fire bricks around the cylinders down to the rear vents and then retort again.

The entire inner part of the retort is lined with 500 mm of ceramic blanket which is important to keep the heat retorting around the cylinders.

The burn time is 8 to 10 hours depending on the grade of wood you are using (8 to 10 hours is time based on OAK, ASH, BEECH or HORNBEAM). This is a lot less than with round kilns. - See more at: http://www.fourseasonsfuel.co.uk/charcoal-retorts-and-kilns/charcoal-retorts-8-0-P-72/#sthash.BJmxYaDn.dpuf
